The references considered for inclusion in, or cited in, the first and second external review drafts of the ISA are available at http://hero.epa.gov/lead (the cited or considered results may also be refined by scientific subjects such as ecological effects, health effects, exposure, toxicokinetics, and atmospheric science).
EPA released this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public (meeting date and location to be specified in a separate Federal Register notice). The draft document does not represent, and should not be construed to represent, any final EPA policy, viewpoint, or determination. EPA will consider any timely public comments submitted when revising the document.
Lead is one of six principal (or “criteria”) pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). The ISA provides a concise review, synthesis, and evaluation of the most policy-relevant science to serve as a scientific foundation for the review of the NAAQS. The CASAC, an independent science advisory committee mandated by Section 109 (d) (2) of the Clean Air Act, is charged with independent scientific review of EPA's air quality criteria.
